Product Description

50kVA/150kV Power Frequency PD-Free AC Withstand Test System

Insulation defects in high-voltage equipment may begin with extremely weak discharge signals that are difficult to identify through conventional withstand testing alone. The 50kVA/150kV Power Frequency PD-Free AC Withstand Test System combines power-frequency AC withstand testing with sensitive partial discharge detection to provide a more comprehensive approach to electrical insulation evaluation.

The system is suitable for various voltage classes and capacities of power transformers, instrument transformers, generators, surge arresters, bushings, GIS, capacitors, switchgear and other high-voltage electrical equipment. Its high-sensitivity detection capability helps capture weak PD signals and identify potential insulation defects, while an intelligent adaptive filtering algorithm suppresses background noise and improves detection stability in complex electromagnetic environments.
